The connector comprises an input circuit(11) for receiving input signals, a matrix/mixer(12) for converting the signals into color difference signals(R-Y,B-Y) to mix with overlapped screen, an encoder(13) for converting the color difference signals of the matrix/mixer(12) into video signals, a Y/C circuit(17) for recording the signals in a head or displaying on the screen, a view finder(18), a micom(19) for controlling memory, overlap and OSD display, a screen overlap controller(20) for controlling overlapping of the last picturing images, an SRAM (21) for storing image signals of the last picturing images or supplying the screen overlap controller(20) with a memory signal, a field correlation detector(22) for comparing the last picturing images of the screen overlap controller(20) with current picturing images to supply the micom(19) with the result.
